===============

|
|
|
This page's purpose is to collect frequently ask questions, problems and workarounds that are reported and known.
|
|
There shall be at least a problem description, an optional explanation if needed, a solution description and the SEB Server version and domain information. For Example:
|
|
|
|
Please also have a look at `Open Issues <https://https://github.com/SafeExamBrowser/seb-server/issues>`_ and/or `Ongoing Discussions <https://github.com/SafeExamBrowser/seb-server/discussions>`_ on the Git-Hub page.

|
|
|
- **Version** : 1.3.x
|
|
- **Domain** : Exam Monitoring
|
|
- **Problem** : SEB connections get lost and ping-times go up for already connected SEB clients
|
|
- **Explanation** : This issue is due to a access token used by SEB client to authenticate on SEB Server that lasts not longer the
|
|
one hour since SEB Server version 1.3 and since SEB client has no new access token request implements yet.
|
|
- **Solution** : A workaround for SEB Server version 1.3.x is to make the access token expiry-date last long enough to minimize the possibility
|
|
that the access token became invalid during a exam. We recommend to set it to 12 hours = 43200 seconds. Therefore please set the following
|
|
SEB Server setup properties in the respective application-prod.properties configuration file of your SEB Server setup:
|
|
|
|
sebserver.webservice.api.admin.accessTokenValiditySeconds=43200
|
|
sebserver.webservice.api.exam.accessTokenValiditySeconds=43200
|
|
|
|
In SEB Server version 1.4 this is already set as default again and we are currently working on new SEB client versions that also
|
|
handle SEB Server communication token expiry by automatically requesting a new access token (with new lifetime) from SEB Server
|
|
when an old access token is not valid any longer.
